Sizing Chart For Models BME-A & BME-UV

There are four regular sizes of Plusaire so how do you decide which size would be right for your home? To help you determine the correct size, here is a simple chart for the homeowner to use.

The calculation must include all floors of your home including the basement whether or not it is finished or heated. This is important as the sizing is based on the cubic feet of air space in the house that is creating the pressure levels.

If your house exceeds 5500 square feet custom units are available, but houses over 4000 square feet usually have more than one furnace. If your house has more than one furnace divide the total sq ft by two and choose two Plusaire units for that size. For very large houses there needs to be a Plusaire unit for each furnace in the house.

BME size # 1 Air or UV.....……..…….……….……………up to 1400 sq ft

BME size # 2 Air or UV…....…..………….…………….….up to 2600 sq ft

BME size # 3 Air or UV…….......…….……………….…..up to 3800 sq ft

BME size # 4 Air ……........…....………………………....up to 5500 sq ft
